## christinacoe72 3 years ago What is the lateral area of a rectangular prism if the base edges are 3 centimeters and 4 centimeters and the height is 6 centimeters? 92 cm2 150 cm2 220 cm2 84 cm2

This is the formula? Perimeter of base x height

2. christinacoe72

12x6 72

6 rectangles. Find the area of the 4 sides. Omit the top and bottom. Add up the 4 sides.

6. Mertsj

3x6+3x6+4x6+4x6=36+48=84

what's the diff b/w a normal area and laternal area?

8. Mertsj

Lateral area is the area of the sides sans the bases. That's why the problem is so specific as to the base edges because the base areas are not part of the lateral (sides) area.

Still didn't got it. sorry.

that makse sence thank u. god i hate geometry.

11. Directrix

84 cm2 The lateral area is the sum of two congruent 4 by 6 rectangles and two congruent 3 by 6 rectangles. That gives 2 (24) plus 2(18) = 84 square cm.

Geo is good..

13. saifoo.khan

that's same as S.A. of a cuboid?

14. Directrix

Yes. The formula is perimeter of the base times the height.
